Schneider Electric LC1D50AD7 TeSys Deca Contactor 3P 3NO AC-3 50 A 42 V AC Coil EverLink BTR Contactor
The Schneider Electric LC1D50AD7 is a 3-pole TeSys Deca Advanced contactor rated 50 A (AC-3) / 22 kW at 400 V, 40 hp at 480 V, with a 42 V AC 50/60 Hz coil and 1 NO + 1 NC auxiliary contacts.
Description
About the LC1D50AD7
About the LC1D50AD7
The Schneider Electric LC1D50AD7 is a 3-pole TeSys Deca contactor rated 50 A AC-3 (up to 440 V) for direct-on-line motor control, switching motors up to 22 kW at 400 V. It carries a 42 V AC coil, a mechanically-linked 1 NO + 1 NC auxiliary contact with mirror-contact certification, and screw-clamp terminals on both power and control circuits for DIN-rail mounting.

Selection Notes
At 50 A AC-3 it covers motors up to 22 kW at 400 V; The 42 V AC coil matches low-voltage control transformers used where reduced control-circuit voltage is a panel safety requirement. The mirror-contact-certified 1 NO + 1 NC auxiliary block confirms power-contact position for safety-circuit feedback without an external contact block.
Applications (manufacturer): Resistive load, Motor control
